This application claims the benefit of U.S. Provisional Application No. 62/835,335, filed on Apr. 17, 2019, the entire content of which is hereby incorporated by reference in its entirety.

FIELD

This application relates generally to toll-like receptor modulator compounds, including diamino pyrido[3,2 D] pyrimidine compounds, and pharmaceutical compositions which, among other things, modulate toll-like receptors (e.g. TLR-8), and methods of making and using them.

BACKGROUND

The toll-like receptor (TLR) family plays a fundamental role in pathogen recognition and activation of innate immunity. Toll-like receptor 8 (TLR-8) is predominantly expressed by myeloid immune cells and activation of this receptor stimulates a broad immunological response. Agonists of TLR-8 activate myeloid dendritic cells, monocytes, monocyte-derived dendritic cells and Kupffer cells leading to the production of proinflammatory cytokines and chemokines, such as interleukin-18 (IL-18), interleukin-12 (IL-12), tumor necrosis factor-alpha (TNF-α), and interferon-gamma (IFN-γ). Such agonists also promote the increased expression of co-stimulatory molecules such as CD8⁺ cells, major histocompatibility complex molecules (MAIT, NK cells), and chemokine receptors.

Collectively, activation of these innate and adaptive immune responses induces an immune response and provides a therapeutic benefit in various conditions involving autoimmunity, inflammation, allergy, asthma, graft rejection, graft versus host disease (GvHD), infection, cancer, and immunodeficiency. For example, with respect to hepatitis B, activation of TLR8 on professional antigen presenting cells (pAPCs) and other intrahepatic immune cells is associated with induction of IL-12 and proinflammatory cytokines, which is expected to augment HBV-specific T cell responses, activate intrahepatic NK cells and drive reconstitution of antiviral immunity. See e.g. Wille-Reece, U. et al. J Exp Med 203, 1249-1258 (2006); Peng, G. et al., Science 309, 1380-1384 (2005); Jo, J. et al., PLoS Pathogens 10, e1004210 (2014) and Watashi, K. et al., J Biol Chem 288, 31715-31727 (2013).

Given the potential to treat a wide array of diseases, there remains a need for novel modulators of toll-like receptors, for example TLR-8. Potent and selective modulators of TLR-8 that have reduced potential for off target liabilities are particularly desirable.

IV. Methods of Preparing Solid Forms of Compound I

The solid forms of Compound I can be prepared by a variety of methods. For example, Compound I can be dissolved in a single solvent system and allowed to crystallize. Alternatively, Compound I can be crystallized from a two-solvent system by dissolving Compound I in a solvent (a good solvent), and then adding an anti-solvent (a bad solvent) to the mixture causing Compound I to crystallize.

The solvent can be any solvent suitable to form a solution. Typically the solvent can be a polar solvent, which in some embodiments is a protic solvent. Other suitable solvents include non-polar solvents. Suitable solvents include, but are not limited to, water, alkanes such as heptanes, hexanes, and cyclohexane, petroleum ether, C₁-C₃ alcohols (methanol, ethanol, propanol, isopropanol), ethylene glycol and polyethylene glycol such as PEG400, alkanoates such as ethyl acetate, propyl acetate, isopropyl acetate, and butyl acetate, acetonitrile, alkanones such as acetone, butanone, methyl ethyl ketone (MEK), methyl propyl ketone (MPK) and methyl iso-butyl ketone (MIBK), ethers such as diethyl ether, methyl-t-butyl ether, tetrahydrofuran, methyl-tetrahydrofuran, 1,2-dimethoxy ethane and 1,4-dioxane, aromatics such as benzene and toluene, halogenated solvents such as methylene chloride, chloroform and carbon tetrachloride, dimethylsulfoxide (DMSO), and dimethylformamide (DMF). Suitable solvents also include, but are not limited to halogenated C₁-C₃ alcohols (trifluoromethanol, trifluoroethanol (TFE), hexafluoroisopropanol (HFIPA)). For example, the solvent can be a polar aprotic solvent such as dichloromethane, N-methylpyrrolidone, tetrahydrofuran, ethyl acetate, acetone, methyl ethyl ketone, dimethylformamide (DMF), acetonitrile (AcCN), dimethyl sulfoxide (DMSO), among others. The solvent can also be a polar protic solvent such as t-butanol, n-propanol, isopropanol, ethanol, methanol, acetic acid, water, among others. The solvent can also be a non-polar solvent, such as hexane, pentanes, petroleum ether, benzene, toluene, diethyl ether, methyl-t-butyl ether, tetrahydrofuran, methyl-tetrahydrofuran, 1,2-dimethoxy ethane and 1,4-dioxane, chloroform, and carbon tetrachloride.

Two or more solvents can be used in a solvent mixture in any suitable ratio. For example, the ratio of a first solvent and a second solvent can be from 10:1 to about 1:10 (volume/volume or weight/weight), or about 10:1 to 1:5, or 10:1 to 1:1, or 10:1 to 5:1, or 5:1 to 1:5, or 5:1 to 1:1, or 4:1 to 1:1, or 3:1 to 1:1, or 2:1 to 1:1. Other solvent ratios include about 10:1, 9:1, 8:1, 7:1, 6:1, 5:1, 4:1, 3:1, 2:1, 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9 or about 1:10 (volume/volume or weight/weight).

The methods of preparing solid forms of Compound I can be performed under any suitable reaction conditions. For example, the methods of preparing the crystalline forms of Compound I can be performed at any suitable temperature, such as, but not limited to, below room temperature, at room temperature, or above room temperature. In some embodiments, the temperature can be from about −78° C. to about 100° C., or from about 0° C. to about 50° C., or from about 10° C. to about 30° C. For example, the reaction mixture be at a temperature of about 20° C., or 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95 or about 100° C.

In some embodiments, the temperature can be the reflux temperature of the particular solvent used in the method. In other embodiments, crystalline forms of Compound I can be heated above about 100° C. such that one crystalline form of Compound I forms a second crystalline form of Compound I.

The methods of preparing solid forms of Compound I can include a variety of other steps. For example, the solvent can be evaporated, a seed crystal can be added to the mixture, the mixture can be heated and cooled a single time or repeatedly, etc. For example, the methods can include heating the reaction mixture to a temperature of about 20° C., or 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95 or about 100° C.

The temperature of the reaction mixture can be changed at any suitable rate. For example, the rate of temperature change can be from about 0.1° C./min to about 10° C./min.

The methods of preparing crystalline forms of Compound I can be performed for any suitable time. For example, the time can be for minutes, hours or days. In some embodiments, the time can be several hours, such as overnight. The methods of preparing crystalline forms of Compound I can be also be performed at any suitable pressure. For example, the pressure can be below atmospheric pressure, at about atmospheric pressure, or above atmospheric pressure.

Crystallization can be induced by methods known in the art, for example by mechanical means such as scratching or rubbing the contact surface of the reaction vessel with e.g. a glass rod. Optionally the saturated or supersaturated solution may be inoculated with seed crystals. The method preparing solid forms of Compound I can also include a seed crystal of crystalline Compound I.

Isolation of the desired crystalline form can be accomplished by removing the solvent and precipitating solvent from the crystals. Generally this is carried out by known methods, such as, filtration, suction filtration, decantation or centrifugation. Further isolation can be achieved by removing any excess of the solvent(s) from the crystalline form by methods known to the one skilled in the art as for example application of a vacuum, and/or by heating.

V. Pharmaceutical Compositions

The solid forms of Compound I provided herein can be administered in the form of pharmaceutical compositions. This disclosure provides pharmaceutical compositions that contain, as the active ingredient, one or more of the solid forms of Compound I described or a pharmaceutically acceptable salt or ester thereof and one or more pharmaceutically acceptable excipients, carriers, including inert solid diluents and fillers, diluents, including sterile aqueous solution and various organic solvents, permeation enhancers, solubilizers and adjuvants. The pharmaceutical compositions may be administered alone or in combination with other therapeutic agents (as indicated in the Combination Therapy section below). Such compositions are prepared in a manner well known in the pharmaceutical art (see, e.g., Remington's Pharmaceutical Sciences, Mace Publishing Co., Philadelphia, Pa. 17th Ed. (1985)); and Modern Pharmaceutics, Marcel Dekker, Inc. 3rd Ed. (G. S. Banker & C. T. Rhodes, Eds.).

The pharmaceutical compositions may be administered in either single or multiple doses by any of the accepted modes of administration of agents having similar utilities, for example as described in those patents and patent applications incorporated by reference, including rectal, buccal, intranasal and transdermal routes, by intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously orally, topically, as an inhalant or via an impregnated or coated device such as a stent, for example or an artery-inserted cylindrical polymer.

One mode for administration is parenteral, particularly by injection. The forms in which the novel compositions of the present disclosure may be incorporated for administration by injection include aqueous or oil suspensions or emulsions, with sesame oil, corn oil, cottonseed oil or peanut oil, as well as elixirs, mannitol, dextrose or a sterile aqueous solution and similar pharmaceutical vehicles. Aqueous solutions in saline are also conventionally used for injection, but less preferred in the context of the present disclosure. Ethanol, glycerol, propylene glycol, liquid polyethylene glycol, and the like (and suitable mixtures thereof), cyclodextrin derivatives, and vegetable oils may also be employed. The proper fluidity can be maintained, for example, by the use of a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like.

Sterile injectable solutions are prepared by incorporating a compound according to the present disclosure in the required amount in the appropriate solvent with various other ingredients as enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the general methods of preparation are vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.

Oral administration is another route for administration of compounds in accordance with the disclosure. Administration may be via capsule or enteric coated tablets or the like. In making the pharmaceutical compositions that include at least one compound described herein, the active ingredient is usually diluted by an excipient and/or enclosed within such a carrier that can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, it can be in the form of a solid, semi-solid or liquid material (as above), which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, sterile injectable solutions and sterile packaged powders.

Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl and propylhydroxy-benzoates; sweetening agents; and flavoring agents.

The compositions of the disclosure can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. Controlled release drug delivery systems for oral administration include osmotic pump systems and dissolutional systems containing polymer-coated reservoirs or drug-polymer matrix formulations. Examples of controlled release systems are given in U.S. Pat. Nos. 3,845,770; 4,326,525; 4,902,514; and 5,616,345. Another formulation for use in the methods of the present disclosure employs transdermal delivery devices (“patches”). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present disclosure in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S. Pat. Nos. 5,023,252, 4,992,445 and 5,001,139. Such patches may be constructed for continuous, pulsatile or on demand delivery of pharmaceutical agents.

In some embodiments, the compositions are formulated in a unit dosage form. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient (e.g., a tablet, capsule, ampoule). The compounds are generally administered in a pharmaceutically effective amount. In some embodiments, each dosage unit contains from 1 mg to 2 g of a compound described herein and for parenteral administration, in some embodiments, from 0.1 to 700 mg of a compound a compound described herein. It will be understood, however, that the amount of the compound actually administered usually will be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered and its relative activity, the age, weight and response of the individual patient, the severity of the patient's symptoms, and the like.

For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present disclosure. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.

The tablets or pills of the present disclosure may be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action or to protect from the acid conditions of the stomach. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer that serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents or mixtures thereof and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in preferably pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a facemask tent or intermittent positive pressure breathing machine. Solution, suspension or powder compositions may be administered, in some embodiments orally or nasally, from devices that deliver the formulation in an appropriate manner.

In one embodiment, this disclosure relates to a pharmaceutical composition comprising a pharmaceutically acceptable excipient or carrier and a therapeutically effective amount of the compound of Compound I as described above or a pharmaceutically acceptable salt, ester, prodrug, stereoisomer or hydrate thereof.

VI. Methods of Use

The solid forms of Compound I described herein can be administered to a subject suffering from a viral infection such as, but not limited to, hepatitis B virus (HBV), hepatitis C virus (HCV), and human immuno-deficiency virus (HIV) in either single or multiple doses by any of the accepted modes of administration known to those who are skilled in the art and as detailed above.

As used herein, an “agonist” is a substance that stimulates its binding partner, typically a receptor. Stimulation is defined in the context of the particular assay, or may be apparent in the literature from a discussion herein that makes a comparison to a factor or substance that is accepted as an “agonist” or an “antagonist” of the particular binding partner under substantially similar circumstances as appreciated by those of skill in the art. Stimulation may be defined with respect to an increase in a particular effect or function that is induced by interaction of the agonist or partial agonist with a binding partner and can include allosteric effects.

As used herein, an “antagonist” is a substance that inhibits its binding partner, typically a receptor. Inhibition is defined in the context of the particular assay, or may be apparent in the literature from a discussion herein that makes a comparison to a factor or substance that is accepted as an “agonist” or an “antagonist” of the particular binding partner under substantially similar circumstances as appreciated by those of skill in the art. Inhibition may be defined with respect to a decrease in a particular effect or function that is induced by interaction of the antagonist with a binding partner, and can include allosteric effects.

As used herein, a “partial agonist” or a “partial antagonist” is a substance that provides a level of stimulation or inhibition, respectively, to its binding partner that is not fully or completely agonistic or antagonistic, respectively. It will be recognized that stimulation, and hence, inhibition is defined intrinsically for any substance or category of substances to be defined as agonists, antagonists, or partial agonists.

As used herein, “intrinsic activity” or “efficacy” relates to some measure of biological effectiveness of the binding partner complex. With regard to receptor pharmacology, the context in which intrinsic activity or efficacy should be defined will depend on the context of the binding partner (e.g., receptor/ligand) complex and the consideration of an activity relevant to a particular biological outcome. For example, in some circumstances, intrinsic activity may vary depending on the particular second messenger system involved. Where such contextually specific evaluations are relevant, and how they might be relevant in the context of the present disclosure, will be apparent to one of ordinary skill in the art.

As used herein, modulation of a receptor includes agonism, partial agonism, antagonism, partial antagonism, or inverse agonism of a receptor.

As will be appreciated by those skilled in the art, when treating a viral infection such as HCV, HBV, or HIV, such treatment may be characterized in a variety of ways and measured by a variety of endpoints. The scope of the present disclosure is intended to encompass all such characterizations.

In one embodiment, the method can be used to induce an immune response against multiple epitopes of a viral infection in a human. Induction of an immune response against viral infection can be assessed using any technique that is known by those of skill in the art for determining whether an immune response has occurred. Suitable methods of detecting an immune response for the present disclosure include, among others, detecting a decrease in viral load or antigen in a subject's serum, detection of IFN-gamma-secreting peptide specific T cells, and detection of elevated levels of one or more liver enzymes, such as alanine transferase (ALT) and aspartate transferase (AST). In one embodiment, the detection of IFN-gamma-secreting peptide specific T cells is accomplished using an ELISPOT assay. Another embodiment includes reducing the viral load associated with HBV infection, including a reduction as measured by PCR testing.

In some embodiments, the present disclosure provides a crystalline form of Compound I for use in the treatment of a hepatitis B viral infection. In some embodiments, the present disclosure provides use of a crystalline form of Compound I for the manufacture of a medicament for the treatment of a hepatitis B viral infection.

Treatment in accordance with the present disclosure typically results in the stimulation of an immune response against HBV or HCV in a human being infected with HBV or HCV, respectively, and a consequent reduction in the viral load of HBV or HCV in the infected person. Examples of immune responses include production of antibodies (e.g., IgG antibodies) and/or production of cytokines, such as interferons, that modulate the activity of the immune system. The immune system response can be a newly induced response, or can be boosting of an existing immune response. In particular, the immune system response can be seroconversion against one or more HBV or HCV antigens.

The viral load can be determined by measuring the amount of HBV DNA or HCV DNA present in the blood. For example, blood serum HBV DNA can be quantified using the Roche COBAS Amplicor Monitor PCR assay (version 2.0; lower limit of quantification, 300 copies/mL [57 IU/mL]) and the Quantiplex bDNA assay (lower limit of quantification, 0.7 MEq/mL; Bayer Diagnostics, formerly Chiron Diagnostics, Emeryville, Calif.). The amount of antibodies against specific HBV or HCV antigens (e.g., hepatitis B surface antigen (HBsAG)) can be measured using such art-recognized techniques as enzyme-linked immunoassays and enzyme-linked immunoabsorbent assays. For example, the amount of antibodies against specific HBV or HCV antigens can be measured using the Abbott AxSYM microparticle enzyme immunoassay system (Abbott Laboratories, North Chicago, Ill.).

Compound I can be administered by any useful route and means, such as by oral or parenteral (e.g., intravenous) administration. Therapeutically effective amounts of Compound I are from about 0.00001 mg/kg body weight per day to about 10 mg/kg body weight per day, such as from about 0.0001 mg/kg body weight per day to about 10 mg/kg body weight per day, or such as from about 0.001 mg/kg body weight per day to about 1 mg/kg body weight per day, or such as from about 0.01 mg/kg body weight per day to about 1 mg/kg body weight per day, or such as from about 0.05 mg/kg body weight per day to about 0.5 mg/kg body weight per day, or such as from about 0.3 μg to about 30 mg per day, or such as from about 30 μg to about 300 μg per day.

Therapeutically effective amounts of Compound I are also from about 0.01 mg per dose to about 1000 mg per dose, such as from about 0.01 mg per dose to about 100 mg per dose, or such as from about 0.1 mg per dose to about 100 mg per dose, or such as from about 1 mg per dose to about 100 mg per dose, or such as from about 1 mg per dose to about 10 mg per dose. Other therapeutically effective amounts of Compound I are about 1 mg per dose, 1.5 mg per dose, 2 mg per dose, 2.5 mg per dose, 3 mg per dose, or 3.5 mg per dose or about 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or about 100 mg per dose. Other therapeutically effective amounts of Compound I are about 100 mg per dose, or about 125, 150, 175, 200, 225, 250, 275, 300, 350, 400, 450, or about 500 mg per dose. A single dose can be administered hourly, daily, or weekly. For example, a single dose can be administered once every 1 hour, 2, 3, 4, 6, 8, 12, 16 or once every 24 hours. A single dose can also be administered once every 1 day, 2, 3, 4, 5, 6, or once every 7 days. A single dose can also be administered once every 1 week, 2, 3, or once every 4 weeks. A single dose can also be administered once every month.

The frequency of dosage of Compound I will be determined by the needs of the individual patient and can be, for example, once per day or twice, or more times, per day. Administration of Compound I continues for as long as necessary to treat the HBV or HCV infection. For example, Compound I can be administered to a human being infected with HBV or HCV for a period of from 20 days to 180 days or, for example, for a period of from 20 days to 90 days or, for example, for a period of from 30 days to 60 days.

Administration can be intermittent, with a period of several or more days during which a patient receives a daily dose of Compound I, followed by a period of several or more days during which a patient does not receive a daily dose of Compound I. For example, a patient can receive a dose of Compound I every other day, or three times per week. Again by way of example, a patient can receive a dose of Compound I each day for a period of from 1 to 14 days, followed by a period of 7 to 21 days during which the patient does not receive a dose of Compound I, followed by a subsequent period (e.g., from 1 to 14 days) during which the patient again receives a daily dose of Compound I. Alternating periods of administration of Compound I, followed by non-administration of Compound I, can be repeated as clinically required to treat the patient.

As described more fully herein, crystalline forms of Compound I can be administered with one or more additional therapeutic agent(s) to a human being infected with hepatitis B virus or hepatitis C virus. The additional therapeutic agent(s) can be administered to the infected human being at the same time as the crystalline form of Compound I, or before or after administration of the crystalline form of Compound I. In some embodiments, the present disclosure provides a crystalline form of Compound I, for use in a method of treating or preventing a hepatitis B viral infection, wherein the crystalline form of Compound I is administered simultaneously, separately or sequentially with one or more additional therapeutic agents for treating a hepatitis B viral infection. In some embodiments, the present disclosure provides use of a crystalline form of Compound I for the manufacture of a medicament for the treatment of a hepatitis B viral infection, wherein the crystalline form of Compound I is administered simultaneously, separately or sequentially with one or more additional therapeutic agents for treating a hepatitis B viral infection.

In another aspect, the present disclosure provides a method for ameliorating a symptom associated with an HBV infection or HCV infection, wherein the method comprises administering to a human subject infected with hepatitis B virus or hepatitis C virus a therapeutically effective amount of the crystalline form of Compound I, wherein the therapeutically effective amount is sufficient to ameliorate a symptom associated with the HBV infection or HCV infection. Such symptoms include the presence of HBV virus particles (or HCV virus particles) in the blood, liver inflammation, jaundice, muscle aches, weakness and tiredness.

In some embodiments, the present disclosure provides a crystalline form of Compound I for use in ameliorating a symptom associated with an HBV infection or HCV infection, wherein the method comprises administering to a human subject infected with hepatitis B virus or hepatitis C virus a therapeutically effective amount of the crystalline form of Compound I, wherein the therapeutically effective amount is sufficient to ameliorate a symptom associated with the HBV infection or HCV infection. In some embodiments, the present disclosure provides use of a crystalline form of Compound I for the manufacture of a medicament for the ameliorating a symptom associated with an HBV infection or HCV infection, wherein the method comprises administering to a human subject infected with hepatitis B virus or hepatitis C virus a therapeutically effective amount of the crystalline form of Compound I, wherein the therapeutically effective amount is sufficient to ameliorate a symptom associated with the HBV infection or HCV infection.

In a further aspect, the present disclosure provides a method for reducing the rate of progression of a hepatitis B viral infection, or a hepatitis C virus infection, in a human being, wherein the method comprises administering to a human subject infected with hepatitis B virus or hepatitis C virus a therapeutically effective amount of Compound I, or a pharmaceutically acceptable salt thereof, wherein the therapeutically effective amount is sufficient to reduce the rate of progression of the hepatitis B viral infection or hepatitis C viral infection. The rate of progression of the infection can be followed by measuring the amount of HBV virus particles or HCV virus particles in the blood.

In another aspect, the present disclosure provides a method for reducing the viral load associated with HBV infection or HCV infection, wherein the method comprises administering to a human being infected with HBV or HCV a therapeutically effective amount of Compound I, or a pharmaceutically acceptable salt thereof, wherein the therapeutically effective amount is sufficient to reduce the HBV viral load or the HCV viral load in the human being.

In a further aspect, the present disclosure provides a method of inducing or boosting an immune response against Hepatitis B virus or Hepatitis C virus in a human being, wherein the method comprises administering a therapeutically effective amount of Compound I, or a pharmaceutically acceptable salt thereof, to the human being, wherein a new immune response against Hepatitis B virus or Hepatitis C virus is induced in the human being, or a preexisting immune response against Hepatitis B virus or Hepatitis C virus is boosted in the human being. Seroconversion with respect to HBV or HCV can be induced in the human being. Examples of immune responses include production of antibodies, such as IgG antibody molecules, and/or production of cytokine molecules that modulate the activity of one or more components of the human immune system.

Induction of seroconversion against HCV or HBV in patients chronically infected with either of these viruses is an unexpected property of Compound I. In clinical practice, an HBV patient, or HCV patient, is treated with Compound I, alone or in combination with one or more other therapeutic agents, until an immune response against HBV or HCV is induced or enhanced and the viral load of HBV or HCV is reduced. Thereafter, although the HBV or HCV virus may persist in a latent form in the patient's body, treatment with Compound I can be stopped, and the patient's own immune system is capable of suppressing further viral replication. In patients treated in accordance with the present disclosure and who are already receiving treatment with an antiviral agent that suppresses replication of the HBV virus or HCV virus, there may be little or no detectable viral particles in the body of the patient during treatment with the antiviral agent(s). In these patients, seroconversion will be evident when the antiviral agent(s) is no longer administered to the patient and there is no increase in the viral load of HBV or HCV.

In the practice of the present disclosure, an immune response is induced against one or more antigens of HBV or HCV. For example, an immune response can be induced against the HBV surface antigen (HBsAg), or against the small form of the HBV surface antigen (small S antigen), or against the medium form of the HBV surface antigen (medium S antigen), or against a combination thereof. Again by way of example, an immune response can be induced against the HBV surface antigen (HBsAg) and also against other HBV-derived antigens, such as the core polymerase or x-protein.

Induction of an immune response against HCV or HBV can be assessed using any technique that is known by those of skill in the art for determining whether an immune response has occurred. Suitable methods of detecting an immune response for the present disclosure include, among others, detecting a decrease in viral load in a subject's serum, such as by measuring the amount of HBV DNA or HCV DNA in a subject's blood using a PCR assay, and/or by measuring the amount of anti-HBV antibodies, or anti-HCV antibodies, in the subject's blood using a method such as an ELISA.

Additionally, the compounds of this disclosure may be useful in the treatment of cancer or tumors (including dysplasias, such as uterine dysplasia). These includes hematological malignancies, oral carcinomas (for example of the lip, tongue or pharynx), digestive organs (for example esophagus, stomach, small intestine, colon, large intestine, or rectum), liver and biliary passages, pancreas, respiratory system such as larynx or lung (small cell and non-small cell), bone, connective tissue, skin (e.g., melanoma), breast, reproductive organs (uterus, cervix, testicles, ovary, or prostate), urinary tract (e.g., bladder or kidney), brain and endocrine glands such as the thyroid. In summary, the compounds of this disclosure are employed to treat any neoplasm, including not only hematologic malignancies but also solid tumors of all kinds.

Hematological malignancies are broadly defined as proliferative disorders of blood cells and/or their progenitors, in which these cells proliferate in an uncontrolled manner. Anatomically, the hematologic malignancies are divided into two primary groups: lymphomas —malignant masses of lymphoid cells, primarily but not exclusively in lymph nodes, and leukemias—neoplasm derived typically from lymphoid or myeloid cells and primarily affecting the bone marrow and peripheral blood. The lymphomas can be sub-divided into Hodgkin's Disease and Non-Hodgkin's lymphoma (NHL). The latter group comprises several distinct entities, which can be distinguished clinically (e.g. aggressive lymphoma, indolent lymphoma), histologically (e.g. follicular lymphoma, mantle cell lymphoma) or based on the origin of the malignant cell (e.g. B lymphocyte, T lymphocyte). Leukemias and related malignancies include acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), acute lymphoblastic leukemia (ALL) and chronic lymphocytic leukemia (CLL). Other hematological malignancies include the plasma cell dyscrasias including multiple myeloma, and the myelodysplastic syndromes.

The solid forms (polymorphs, solvates and hydrates) of Compound I were characterized by a variety of the following methods.

XRPD patterns were collected with a PANalytical X'Pert PRO MPD diffractometer using an incident beam of Cu Kα radiation produced using a long, fine-focus source and a nickel filter. The diffractometer was configured using the symmetric Bragg-Brentano geometry. Prior to the analysis, a silicon specimen (NIST SRM 640e) was analyzed to verify the observed position of the Si 111 peak is consistent with the NIST-certified position. A specimen of the sample was prepared as a thin, circular layer centered on a silicon zero-background substrate. Antiscatter slits (SS) were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the sample and Data Collector software v. 2.2b.

Differential Scanning Calorimetry (DSC) data were collected using a TA Instruments 2920 and Q2000 differential scanning calorimeter. Temperature calibration was performed using NIST-traceable indium metal. The sample was placed into a T zero aluminum DSC pan, covered with a lid and crimped. The weight was then accurately recorded. A weighed aluminum pan configured as the sample pan was placed on the reference side of the cell. The sample was heated from −30° C. to 250° C. at 10° C./minute.

Thermogravimetric Analysis (TGA) data were collected using a TA Instruments Discovery thermogravimetric analyzer. Temperature calibration was performed using nickel and Alumel™. Each sample was placed in an aluminum pan and inserted into the TG furnace. The furnace was heated under a nitrogen purge. The sample was heated from ambient to 350° C. at 10° C./minute.

Moisture sorption/desorption data were collected on a VTI SGA-100 Vapor Sorption Analyzer. NaCl and PVP were used as calibration standards. Samples were not dried prior to analysis. Sorption and desorption data were collected over a range from 5% to 95% RH at 10% RH increments under a nitrogen purge. The equilibrium criterion used for analysis was less than 0.0100% weight change in 5 minutes with a maximum equilibration time of 3 hours. Weight percentages reported in the data section are relative to the total sample mass introduced prior to equilibration at 5% RH as measured on the instrument.

Example 1. Preparation of Compound I

To a nitrogen flushed 50-L jacketed reactor was charged Compound A (2.69 kg, 6.07 moles, 1.0 equiv). This was followed by the addition of dichloromethane (10.13 L, 13.44 kg). Agitation was set to 175 RPM and the contents were agitated until a solution was observed. Trifluoroacetic acid (4.53 L, 6.75 kg) was charged at a rate such that the internal temperature did not exceed 35° C. (ca. 30 min.). After the addition of trifluoroacetic acid, the jacket was set to 46° C. (to maintain a gentle reflux). The contents were agitated at this temperature for 3 h and then the jacket was set to 15° C. Once the internal temperature reached 20° C., ethanol (denatured from n-heptane) (8.56 L, 6.75 kg) was charged and the contents were allowed to agitate at 20° C. for 14 h. After this amount of time, the heterogeneous contents were filtered through a benchtop poly-filter into a nitrogen flushed 100-L jacketed reactor.

Dichloromethane (5.21 L, 6.91 kg) was charged to the 50-L reactor and the solution was rinsed through the filter into the 100-L reactor. To the 100-L reactor was then charged water (15.5 L, 15.5 kg) and ethyl acetate (19.0 L, 17.0 kg). Agitation was set to 175 RPM and the jacket was set to 87° C. The contents were allowed to heat to reflux for 30 min. After this amount of time, the jacket was set to 20° C. The aqueous layer was discharged. To the reactor was charged water (18.4 L. 18.4 kg), and agitation was set to 200 RPM. 30% w/w NaOH (8.61 kg) was charged and the contents were agitated for 30 min. at 30° C. (jacket was set at 40° C.). Ethyl acetate (45.0 L, 40.4 kg) was then charged and the jacket was set to 55° C. Once the internal temperature reached 45° C., the contents were agitated at 200 RPM for 30 min. After this amount of time, agitation was stopped and the phases were allowed to separate and the aqueous layer was discharged. 4.5% w/w aqueous sodium bicarbonate (prepared from 605 g sodium bicarbonate and 12.8 kg water) solution was charged and the contents were agitated at 200 RPM at an internal temperature of 45° C. for 30 min. After this amount of time, agitation was stopped and the layers were allowed to separate. The aqueous layer was discharged and the jacket was set to 20° C. The contents were aged at this temperature under nitrogen for 14 h. The jacket was then set to 55° C. Once the internal temperature reached 45° C., 4.5% w/w aqueous sodium bicarbonate (prepared from 605 g sodium bicarbonate and 12.8 kg water) was charged and the contents were agitated (200 RPM) at 45° C. for 30 min. Agitation was then stopped, the phases were allowed to separate and the aqueous layer was discharged. 4.5% w/w aqueous sodium bicarbonate (prepared from 605 g sodium bicarbonate and 12.8 kg water). The contents were agitated (200 RPM) at 45° C. for 30 min. Agitation was then stopped, the phases were allowed to separate and the aqueous layer was discharged. Water (13.6 L, 13.6 kg) was added and the contents were agitated (150 RPM) at 45° C. for 30 min. After this amount of time, agitation was stopped and the phases were allowed to separate and the aqueous layer was discharged.

Alternatively, to a nitrogen flushed reaction vessel was charged Compound A (scaling factor, 1.0 part). This was followed by the addition of dichloromethane (2.5 parts). The contents were agitated until a homogenous solution was observed. Trifluoroacetic acid (2.0 parts) was charged at a rate such that the internal temperature did not exceed 35° C. (ca. 30 min.). After the addition of trifluoroacetic acid, the jacket was set to maintain an internal temperature at ca. 30° C. The contents were agitated at this temperature for approximately 10 h and then the jacket was set to 22° C. Once the internal temperature reached 22° C., ethanol (2.0 parts) was charged and the contents were allowed to agitate at 22° C. for 14 h. After this amount of time, the contents were filtered. The filter was rinsed with ethanol (2.0 parts) and the contents were distilled to approximately 3 L/kg. The contents were cooled to 22° C. and ethanol (1 part) and water (1 part) were charged to the contents. To this was charged 50% wt/wt aqueous sodium hydroxide solution (ca. 0.7 parts) until a pH of 12-14 was achieved. The internal temperature of the contents were adjusted to 22° C. and water (3.0 parts) was charged over 30 min. The contents were cooled to approximately 0° C. over 2 h and held at this temperature for 2 h. The slurry was filtered and the cake was rinsed with a 1:1 wt/wt ratio of water and ethanol (2 parts). The contents were dried at 45° C. until a constant weight is achieved. Compound I (Form I) was discharged and packaged.

Example 2. Form I (Ethyl Acetate)

The reactor was configured for vacuum distillation and the jacket was set to 70° C. and agitation was set to 150 RPM. The solvent was removed via vacuum distillation to ca. 30 L.

Ethyl acetate (45 L, 40.4 kg) was charged and the reactor was heated to 70° C., agitation was set to 150 RPM and the pressure was reduced. The solvent was removed via vacuum distillation to ca. 30 L. The jacket was set to 35° C. and the reactor was backfilled with nitrogen. The ethyl acetate distillation sequence was repeated as described 5 X. Final volumes for the five distillations were ca. 30 L after charging 45 L ethyl acetate for each sequence. The contents were sampled for water content (target <0.5% H₂O). After passing the water content criteria, the jacket was heated to 70° C., agitation was set to 150 RPM and the pressure was reduced and the distillation was continued to ca. 22 L. The jacket was set to 35° C. and the reactor was backfilled with nitrogen. Ethyl acetate (15 L, 13.5 kg) was charged and the contents were polish filtered through a 1.0 m filter into the crystallizer. The jacket on the crystallizer was set to 70° C. and agitation was set to 150 RPM. The pressure of the vessel was reduced and the distillation was continued to ca. 18 L. Once this target volume was reached, the crystallizer was backfilled with nitrogen and the jacket was set to 87° C. Ethyl acetate (9.5 L, 8.5 kg) was charged and the contents were agitated until a homogenous solution was observed. After all solids dissolved, a cooling ramp from 85° C. to 20° C. over 8 h was initiated.

The solids were filtered and the wet-cake was washed with ethyl acetate (6.1 L, 5.5 kg). The jacket on the filter was set to 46° C. and the contents were dried for 24 h under reduced pressure with a nitrogen bleed. Compound I (Form I) was isolated in good purity (99.6% Assay, 99.7% AN).

Optionally, Compound I (1.2 kg, 4.0 mol) was charged to a 50-L jacketed reactor followed by ethyl acetate (25 L, 22 kg). The jacket on the reactor was set to 87° C. and agitation was set to 150 RPM. The contents were agitated until a solution was observed. After all solids dissolved, a cooling ramp from 85° C. to 20° C. over 8 h was initiated. The solids were filtered and the wet-cake was washed with ethyl acetate (6.1 L, 5.5 kg). The jacket on the filter was set to 46° C. and the contents were dried for 24 h under reduced pressure with a nitrogen bleed. Compound I Form I was isolated.
